Definitions
- the present invention relates to a color liquid crystal display and, particularly, to a color liquid crystal display which has high display qualities and is highly reliable.
- color liquid crystal displays have attracted remarkable attention as flat displays.
- One example of these color liquid crystal displays has a schematic structure comprising a color filter substrate including a black matrix, a colored layer consisting of plural colors (three primary colors: red (R), green (G) and blue (B)), a transparent electrode and an oriented layer, a counter electrode substrate including a thin film transistor (TFT element), a pixel electrode and an oriented layer, and a liquid crystal layer formed by opposing these both substrates to each other with a predetermined gap between them, sealing by a sealing member and filling a liquid crystal material in the gap.
- TFT element thin film transistor
- the aforementioned gap is just the thickness of the liquid crystal.
- the thickness of the above liquid crystal layer namely the distance between the color filter substrate and the counter electrode substrate must be kept strictly constant to enable exhibition of high display efficiencies which is required to a color liquid crystal display, including high speed responsibility, high contrast ration and wide angle of view. This is the reason why the following settings are taken.
- glass beads or plastic beads with a predetermined diameter and uniform grain diameter are dispersed as a spacer in either one of the color filter substrate and the counter electrode substrate.
- both substrates are applied to each other and sealed by a sealing member.
- the distance of the gap between both substrates, namely the thickness of the liquid crystal layer is set corresponding to the diameter of the glass beads or plastic beads.
- a color liquid crystal display in which an organic film is formed inside of the sealing member to prevent the liquid crystal layer from being contaminated with the reaction gas and eluents from the sealing member (Japanese Patent Application Laid-Open (JP-A) No. H8-328024).
- a step of forming the organic film by a photolithographic method is required in addition to a step of forming the colored layer comprising the black matrix and three colors of R, G and B.
- glass beads or plastic beads as a spacer there is the case where the thickness of the liquid crystal layer is not formed uniformly and the orientation of liquid crystal molecules is disordered when the distribution of the spacer is nonuniform and the spacer are present on display pixels, giving rise to the problem of a reduction in the display efficiencies including contrast ration.
- the present invention has been made in view of the above problems and has an object of providing a color liquid crystal display which is provided with a shielding member disposed between a sealing member and a display zone to prevent the liquid crystal layer from being contaminated with liquid crystal layer-contaminants from the sealing member wherein the above shielding member is formed of a material excluding substances, which adversely affect the liquid crystal layer, and/or can be produced in a simple production process.
- a color liquid crystal display comprising at least a color filter substrate provided with a colored layer with plural colors formed into a predetermined pattern in a display zone on a transparent substrate, a counter electrode substrate disposed opposite to and with a predetermined gap from the color filter substrate, a sealing member disposed outside of the display zone to seal the gap formed between both substrates, a liquid crystal layer formed by filling a liquid crystal material in the gap formed between both substrates and sealed by the sealing member and a shielding member disposed between the sealing member and the display zone to prevent the liquid crystal material contained in the liquid crystal layer from being contaminated with contaminants from the sealing member, the shielding member being formed of a material which works such that the voltage retention and residual DC ( ⁇ E) of the liquid crystal material after the impurity-extraction treatment is 80% or more and 0.5 V or less respectively.
- ⁇ E voltage retention and residual DC
- the color liquid crystal display of the present invention is provided with the shielding member disposed between the sealing member and the display zone in this manner.
- the liquid crystal material of the liquid crystal layer never be contaminated with contaminants from the sealing member.
- the shielding member is formed of such a material as aforementioned, the contamination of the liquid crystal material which is caused by the material of the shielding member is prevented, decreasing the possibilities of white unevenness and seizure of the liquid crystal.
- the shielding member is formed of a material which does not contain pigments, pigment derivatives, dyes or dye derivatives. This is because these pigments, pigment derivatives, dyes or dye derivatives contaminate the liquid crystal material highly possibly though it depends upon the types of these materials and hence there is the case where the shielding member cannot work such that the voltage retention of the liquid crystal material is 80% or more and the residual DC ( ⁇ E) of the liquid crystal material is 0.5 V or less when the liquid crystal material is subjected to impurity-extraction treatment using a material containing a pigment or pigment derivative or a dye or dye derivative.
- a color liquid crystal display comprising at least a color filter substrate provided with a colored layer with plural colors formed into a predetermined pattern in a display zone on a transparent substrate, a counter electrode substrate disposed opposite to and with a predetermined gap from the color filter substrate, a sealing member disposed outside of the display zone to seal the gap formed between both substrates, a liquid crystal layer formed by filling a liquid crystal material in the gap formed between both substrates and sealed by the sealing member, a columnar convex portion formed so as to keep the gap between both substrates constant and a shielding member disposed between the sealing member and the display zone to prevent the liquid crystal material of the liquid crystal layer from being contaminated with contaminants from the sealing member and formed of the same material as the columnar convex portion.
- the shielding member Since the material of the shielding member is formed of the same material as the columnar convex portion like this, the shielding member can be produced at the same time when the columnar convex portion is formed. Accordingly, no additional photolithographic step only for producing the shielding member is not required and a color liquid crystal display having a shielding member can be thereby produced in a simple production process. Also, the columnar convex portion which serves to uniform the gap between both substrates can be produced at the same time when the shielding member is produced. It is therefore unnecessary to use glass beads or plastic beads as a spacer.
- the shielding member is formed of a material which works such that the voltage retention and residual DC ( ⁇ E) of the liquid crystal material after the impurity-extraction treatment is 80% or more and 0.5 V or less respectively. This makes it possible to produce a color liquid crystal display having both advantages of the color liquid crystal displays according to the first and second aspects of the present invention.
- the shielding member is formed of the same material as the columnar convex portion and a protective layer. This is because when the shielding member, the columnar convex portion and the protective layer are formed of the same materials in this manner, the three can be formed in one step simultaneously and hence the step of producing the color liquid crystal display can be simplified, which can reduce production costs.
- the shielding member is formed on a black matrix disposed outside of the display zone.
- the formation of a part or all of the shielding member formed on the black matrix disposed outside of the display zone causes the formation of a clearance between the shielding member and the either one of substrates.
- the shielding member has the same height as the columnar convex portion. Since the columnar convex portion is formed on the colored layer, the altitude of the columnar convex portion from the substrate surface is higher than that of the shielding member formed on the black matrix by the difference in thickness between the colored layer and the black matrix. Because the gap between the color filter substrate and the counter electrode substrate is defined by the altitude of the columnar convex portion, the clearance is formed between the shielding member and the substrate resultantly.
- the shielding member is formed on at least one dummy colored layer formed on the black matrix disposed outside of the display zone.
- the shielding member has the same altitude as or slightly higher altitude than that of the columnar convex portion when the shielding member and the columnar convex portion are formed at the same time. It is therefore possible to use the shielding member, like the columnar convex portion, as the spacer which serves to keep a predetermined gap between both substrates. This structure is also useful particularly when it is intended to prevent the sealing member perfectly from being in contact with the liquid crystal material.
- the shielding member in the vicinity of a liquid crystal-sealing port and/or a straightening vane of a liquid crystal-sealing port is produced by forming a convex portion formed of the same material as the columnar convex portion on at least one dummy colored layer formed on the black matrix.
- the shielding member in the vicinity of the sealing port and/or the straightening vane of the sealing port is structured by forming a convex portion formed of the same material as the columnar convex portion on at least one dummy colored layer as aforementioned is that the liquid crystal material-sealing port is prevented from being made narrower, which can avoid disorders such as a reduction in the filling rate of the liquid crystal and allows the production of the display in a simpler process.
- the shielding member is formed on a transparent electrode.
- the transparent electrode can be led out of the sealing member with ease thereby wiring easily.
- the transparent electrode is laid on the shielding member, there is the case where it is necessary to form an insulated layer on the opposite substrate. In this case, a predetermined width is required in light of accuracy. If the shielding member is formed on the transparent electrode, it is unnecessary to form the insulated layer on the opposite substrate and hence a narrow architrave configuration can be attained.

When the voltage applied between electrodes located on both sides of the liquid crystal layer cannot be maintained, the possibility of the generation of the white unevenness will increase.
- the residual DC ( ⁇ E) is a characteristic corresponding to the seizure which is one of display defects. In order to prevent the seizure, it is necessary to make the residual DC ( ⁇ E) as small as possible to prevent unnecessary voltage from being applied continuously to the liquid crystal layer after the voltage applied to the liquid crystal layer is released.

- the color liquid crystal display of this embodiment may be produced using a customarily available method of the production of a color liquid crystal display.
- the method of producing a color filter substrate which will be explained in a second embodiment may be used.
- the shielding member which is the notable feature of this embodiment may be formed by a separate photolithographic process. Also, it may be formed at the same time, when the columnar convex portion is formed, depending upon material, for example, in the case of using the same material as the columnar convex portion which functions as a spacer.
- a shielding member formed by laminating colored layers may be used if it fulfills the aforementioned requirements for the shielding member material.

- a first feature of the second embodiment is in the point that the shielding member is provided between the sealing member and the display zone to prevent the liquid crystal material of the liquid crystal layer from being contaminated with contaminants from the sealing member. This point is the same as in the aforementioned first embodiment and so its explanations are omitted here.
- this embodiment comprises the columnar convex portion formed so as to keep the gap between the color filter substrate and the counter electrode substrate constant and the shielding member formed of the same material as the columnar convex portion. Since this embodiment is provided with the shielding member formed of the same material as the columnar convex portion used as a spacer which keeps the gap between both substrates constant, the shielding member can be produced at the same time when the columnar convex portion is formed. Accordingly, no additional photolithographic step only for producing the shielding member is not required and a color liquid crystal display having a shielding member can be thereby produced in a simple production process.
- UV-curable resins will be explained.
- the UV-curable resin used in this embodiment those comprising a monomer or an oligomer which has at least one or more functional groups and increases in the molecular weight and forms a cross-linking structure by ion polymerization or radical polymerization which runs by ions or radicals produced by applying curing energy beams to a photopolymerization initiator.
- the functional group so-called here is an atomic group or bonding form, such as a vinyl group, carboxyl group or hydroxyl group, which is a cause of a reaction.
- acrylic types such as epoxyacrylate, urethane acrylate, polyester acrylate, polyether acrylate and silicon acrylate and non-acrylic types such as unsaturated polyester/styrene types and polyene/styrene types.
- acrylic types are preferred in view of curing speed and wide selectivity of various properties. Typical examples of such an acrylic type are shown below.

- thermosetting resins As the thermosetting resin composition used in the present invention, those cured by addition of heat energy and the strength after being cured is enough to give a function as a spacer may be exemplified.
- Typical examples of the thermosetting resin include a polycarbonate, polymethylmethacrylate, polymers or copolymers of methylphthalate, polyethylene terephthalate, polystyrene, diethylene glycol bisallyl carbonate, acrylonitrile/styrene copolymers and poly(-4-methylpenetene-1).
- the columnar convex portion and the shielding member are preferably formed of transparent materials.
- the materials used for these portion and member are not limited to transparent materials and those colored by mixing pigments or the like are acceptable.
- the shielding member and the columnar convex portion used in this embodiment may be formed either on the side of the color filter substrate or on the side of the counter electrode substrate.
- the shielding member and the columnar convex portion are preferably formed on the same substrate since it is effective to form the both at the same time.
- the shielding member among these materials for the shielding member, it is preferable to use materials which work such that the voltage retention and residual DC ( ⁇ E) of the liquid crystal material after the impurity-extraction treatment is 80% or more and 0.5 V or less respectively.
- the use of such a material prevents the liquid crystal material contained in the liquid crystal layer from being contaminated with the shielding member and the columnar convex portion and hence suppress disorders of liquid crystal display. This point is the same as in the aforementioned first embodiment and hence further explanations are omitted.
- the material used for the shielding member is preferably the same as that of the protective layer. This is because when the shielding member, the columnar convex portion and the protective layer are formed of the same materials in this manner, these three parts can be formed on the substrate simultaneously and hence the step of producing the color liquid crystal display can be simplified, which can reduce production costs.
- FIG. 4 is a partly sectional view of an example of this embodiment.
- a color liquid crystal display 1 ′ of this embodiment has a structure in which a color filter substrate 2 ′ is opposed to a counter electrode substrate 3 with a predetermined gap and the peripheral portion of the substrate is sealed by a sealing member 4 .
- a shielding member 14 is formed inside of the sealing member 4 .
- the counter electrode substrate 3 and sealing member 4 of this color liquid crystal display 1 ′ are the same as those in the aforementioned example shown in FIG. 2 and hence further explanations are omitted.
- a colored layer 13 ( 13 R, 13 G and 13 B) on the color filter substrate 2 ′ and a black matrix 12 ( 12 a and 12 b ) are the same as those in the aforementioned example shown in FIG. 2, and hence further explanations are also omitted.
- the columnar convex portion 18 to be formed on the color filter substrate 2 ′ in the example shown in FIG. 4 is provided at predetermined plural positions in the display zone A and has a height corresponding to the gap between the color filter substrate 2 ′ and the counter electrode substrate 3 .
- a transparent electrode 16 is formed on the black matrix 12 b formed on the display zone A and the peripheral zone Be On the transparent electrode 16 , the shielding member 14 and the columnar convex portion 18 are formed at the same time.
- an oriented layer 17 is further formed on the shielding member 14 and the columnar convex portion 18 .
- the above columnar convex portion 18 is disposed on the colored layer 13 , which is formed on the black matrix 12 a such that it overlaps on the black matrix 12 a , and projects more externally than the colored layer 13 by a length ranging from about 2 to 10 ⁇ m.
- the length projected may be properly designed on the basis of the thickness required for the liquid crystal layer 5 of the color liquid crystal display 1 ′.
- the formation density of the columnar convex portion 18 may be properly designed taking unevenness of the thickness, opening ratio and the like of the liquid crystal layer 5 into consideration.
- the columnar convex portion 18 is formed so as to perform a function necessary and sufficient as a spacer in a ratio of one to one pair of red pattern 13 R, green pattern 13 G and blue pattern 13 B which are consist of the colored layer 13 .
- No particular limitation is imposed on the shape of the columnar convex portion and it may take each of various forms, e.g., a cylindrical form or prismatic form.
- the shielding member 14 is formed on the black matrix 12 b formed outside of the display zone A whereas the columnar convex portion 18 is formed on the colored layer 13 .
- the shielding member 14 and the columnar convex portion 18 are formed simultaneously by, for example, a lithographic process and hence with the same heights.
- Each total height of the shielding member 14 and the columnar convex portion 18 namely each altitude of the both from the surface of the transparent substrate 11 of the color filter substrate 2 ′ is set such that the columnar convex portion 18 is higher than the shielding member 14 by the difference in thickness between the colored layer 13 and the black matrix 12 b .
- the columnar convex portion has a function as a spacer keeping both substrates at a constant interval and hence a fixed clearance is formed between the shielding member 14 and the counter electrode substrate 3 .
- a clearance is formed between the shielding member 14 and the counter electrode substrate 3 in this manner, a part of the liquid crystal material is flowed into between the shielding member 14 and the sealing member 4 from the clearance when the liquid crystal material is injected. If the liquid crystal material is made to flow into between the shielding member 14 and the sealing member 4 , this alleviates the suffering from the disadvantage that air bubbles present between the shielding member 14 and the sealing member 4 intermingle with the liquid crystal layer 5 in the subsequent use or the like.
- FIG. 5 is a partly sectional view showing another example of this embodiment.
- the example shown in FIG. 5 differs from the example shown in FIG. 4 in the point that a shielding member 14 is formed on a dummy colored layer 13 R′ in the example shown in FIG. 5 .
- This dummy colored layer 13 R′ has been formed in advance at the position, where the shielding member 14 on a black matrix 12 b formed outside of the display zone is to be formed, when forming a colored layer 13 R.
- a transparent electrode 16 is formed on the dummy colored layer 13 R′.
- the shielding member 14 is further formed on the dummy colored layer 13 R′.
- the shielding member 14 in this example is therefore formed on the dummy colored layer 13 R′ formed on the black matrix 12 b .
- the shielding member 14 and the columnar convex portion 18 are formed of the same materials simultaneously like in the example shown in FIG. 4, the heights of the both are almost the same.
- Each altitude of the shielding member 14 and the columnar convex portion 18 from the surface of the transparent substrate 11 on the side of the color filter substrate 2 ′ is set such that the both are almost the same or the shielding member 14 is slightly higher than the columnar convex portion 18 .
- the shielding member 14 is formed on the dummy colored layer 13 R′.
- This embodiment is not limited to this example and there is no particular limitation is imposed on the arrangement of the shielding member 14 insofar as it is formed after at least one dummy colored layer is laminated, for instance, after two dummy colored layers are laminated, the shielding member 14 and the columnar convex portion 18 are formed at the same time on the these colored layers.
- the dummy colored layer 13 R′ is covered with the transparent electrode 16 .
- the dummy colored layer 13 R′ is not covered with the transparent electrode 16 or the like unlike the above, preferably the dummy colored layer 13 R′ is formed such that the surface of the dummy colored layer 13 R′ on the side of the liquid crystal layer 5 is covered with the shielding member 14 .
- the dummy colored layer generally contains pigments or pigment derivatives which adversely affect the display performance of the liquid crystal material highly possibly and if these pigments or pigment derivatives are brought into contact with the liquid crystal material sealed in the liquid crystal layer, there are high possibilities of the display performance of the liquid crystal material being adversely affected by these materials.
- the shielding material is formed on the dummy colored layer and how many dummy colored layers are laminated are properly determined according to the necessity of a gap between the shielding member and the substrate, the propriety of contact between the sealing member and the liquid crystal material and a clearance required between the substrates in the periphery of the display zone.
- the shielding member may be all formed on the dummy colored layer and also on the black matrix.
- the shielding member may be formed such that its height is changed in parts, for instance, a part of the shielding member is formed on the dummy colored layer and other parts are formed on the black matrix.
- a shielding member in the vicinity of a liquid crystal-sealing port (a shielding member within a range of 10 to 20 mm from the end of the shielding member) for filling the liquid crystal material in the liquid crystal layer and/or a straightening vane formed in the sealing port for the liquid crystal material is formed on at least one dummy colored layer.
- the liquid crystal material can be inefficiently filled if no certain clearance is formed between both substrates when the liquid crystal material is filled. This is the reason why the above structure is preferred.
- the reminder of the shielding material in this case may be formed all on the black matrix or partly on the dummy colored layer.
- the shielding member 14 and the columnar convex portion 18 are formed on the transparent electrode 16 .
- the shielding member 14 and the columnar convex portion 18 are formed on the transparent electrode 16 like this, it is unnecessary to form an insulated layer on the side of the counter electrode substrate 3 , which increases the freedom of designing of wiring on the side of the counter electrode substrate and the freedom of designing of a transparent electrode pattern on the color filter substrate and hence a narrow architrave configuration can be attained.
- a red pattern 13 R is formed in a red pattern-forming zone between the black matrixes 12 a in a display zone A and at the same time, a dummy colored layer 13 R′ is formed on the black matrix 12 b in a zone B (see FIG. 6 (A)).
- the above black matrix 12 may be formed, for example, as follows. First, a shading layer consisting of, for example, a metal thin film made of, for example, chromium which is formed by a sputtering method, vacuum deposition method or the like and a resin layer containing shading particles such as carbon fine particles is formed on the substrate 11 . A photosensitive resist layer is formed on the shading layer by using a positive type or a negative type photoresist. Next, the photosensitive resist layer is exposed through a photomask for black matrix and developed. The exposed shading layer is etched and thereafter the photoresist layer left unremoved is removed to thereby form the black matrix 12 .
- a shading layer consisting of, for example, a metal thin film made of, for example, chromium which is formed by a sputtering method, vacuum deposition method or the like and a resin layer containing shading particles such as carbon fine particles is formed on the substrate 11 .
- a photosensitive resist layer is formed on the shading layer by using a positive
- the above red pattern 13 R and the dummy colored layer 13 R′ are formed, for example, by the following method. Firstly, a red-photosensitive resin layer containing a red colorant is formed on the substrate 11 so as to cover the black matrix 12 . The red-photosensitive resin layer is exposed through a given photomask and developed to form the red pattern 13 R in the red-pattern forming zone on the substrate 11 and at the same time, the dummy colored layer 13 R′ on the black matrix 12 b.
- a green pattern 13 G is formed on a green-pattern forming zone on the substrate 11 and further a blue pattern 13 B is formed on a blue-pattern forming zone on the substrate 11 .
- a transparent electrode 16 is formed so as to cover the colored layer 13 , the dummy colored layer 13 R′ and the black matrix 12 b (see FIG. 6 (B)).
- the transparent electrode 16 may be formed using indium tin oxide (ITO), zinc oxide (ZnO), tin oxide (SnO) or the like or alloys of these compounds by a usual filming method such as a sputtering method, vacuum deposition method or CVD method.
- a negative type transparent photosensitive resin layer 30 is formed on the substrate 11 so as to cover the substrate 11 (FIG. 6 (C)).
- the transparent photosensitive resin layer 30 may be formed by applying a well-known negative type transparent photosensitive resin composition, whose viscosity has been optimized, by a well-known means such as a spin coater or roll coater, followed by drying.
- the thickness of the transparent photosensitive resin 30 may be properly set according to each height required for the shielding member 14 and columnar convex portion 18 .
- the negative type transparent photosensitive resin layer 30 is exposed through a photomask M (see FIG. 6 (D)).
- a mask may be provided to prevent the periphery of the substrate 11 from being exposed to perform the above-mentioned curing treatment.
- the transparent photosensitive resin layer 30 is developed using a developing solution. By this development, the transparent photosensitive resin layer 30 on the portions where the shielding member 14 and the columnar convex portion 18 are formed is left undissolved and the transparent photosensitive resin layer 30 on other regions is dissolved and removed (see FIG. 6 (E)).
- the shielding member 14 and the columnar convex portion 18 are formed at the same time.
- the oriented layer is formed, followed by carrying out predetermined curing treatment to obtain the color filter substrate 2 ′′.
- a negative type transparent photosensitive resin composition is used in the aforementioned production method
- a well-known positive type transparent photosensitive resin composition may be used to form the color filter substrate.
- a positive type transparent photosensitive resin layer is formed so as to cover these layers. Then, the positive type transparent photosensitive resin layer is exposed using a photomask for forming the shielding member 14 and the columnar convex portion 18 and developed.
- the positive type transparent photosensitive resin layer on the portions where the shielding member 14 and the columnar convex portion 18 are to be formed is left undissolved and other regions are dissolved and removed, to thereby form the shielding member 14 and the columnar convex portion 18 at the same time.
- the shielding member 14 and the columnar portion 18 may be formed by forming a transparent resin layer corresponding to each height required for the shielding member 14 and columnar convex portion 18 and forming a resist layer at the positions where the shielding member 14 and the columnar convex portion 18 on the transparent resin layer are to be formed, followed by etching.
- the shielding member and the columnar convex portion are formed of the same materials in this manner, the both can be formed at the same time by the method mentioned above. Therefore, a color filter substrate provided with the shielding member and the columnar convex portion can be produced without carrying out a new additional step. This decreases the production cost and hence the resulting color liquid crystal display can be provided at a low price.
- This example shows one in which the shielding member, the columnar convex portion and the protective layer are formed of the same materials at the same time.
- This example is preferably used for a color filter substrate for a color liquid crystal display using an IPS system.
- a red pattern 13 R is formed in a red pattern-forming zone between black matrixes 12 a in a display zone A and at the same time, a dummy colored layer 13 R′ is formed on a black matrix 12 b in a zone B (see FIG. 7 (A)).
- a red pattern 13 R is formed in a red pattern-forming zone between black matrixes 12 a in a display zone A and at the same time, a dummy colored layer 13 R′ is formed on a black matrix 12 b in a zone B (see FIG. 7 (A)).
- a negative type transparent photosensitive resin layer 30 is formed on the substrate 11 so as to cover the substrate 11 in the same manner as in the example shown in FIG. 6 (see FIG. 7 (B)). Then, the negative type transparent photosensitive resin layer 30 is exposed through a photomask M (see FIG. 7 (C)). In succession, curing treatment of the transparent photosensitive resin layer 30 is performed either before or after the exposure so that the transparent photosensitive resin layer 30 in the unexposed region (regions other than the positions where the shielding member 14 and the columnar convex portion 18 are to be formed) is left in a desired thickness enough to form a transparent protective layer 15 in the developing step mentioned later.
- Examples of the curing treatment include a process in which the transparent photosensitive resin layer 30 is heated at a temperature enabling a curing reaction to proceed, for example, at a temperature higher than the prebaking temperature used in usual photolithography and a process in which the entire of the transparent photosensitive resin layer 30 is exposed at a predetermined exposure value smaller than that sufficient to cure the transparent photosensitive resin layer 30 completely.
- a curing reaction is run enough in the portions (portions exposed through the photomask M) of the transparent photosensitive layer 30 where the shielding member 14 and columnar convex portion 18 are to be formed whereas a curing reaction is run in other positions (portions unexposed through the photomask M) to the extent that the transparent protective layer 15 can be formed.
- the transparent photosensitive resin layer 30 is developed using a developing solution. As outlined above, each optimum curing reaction is run in the region where the transparent protective layer 15 is to be formed and at the positions where the shielding member 14 and the columnar convex portion 18 are to be formed. By virtue of this phenomenon, the transparent photosensitive resin layer 30 at the positions where the shielding member 14 and the columnar convex portion 18 are to be formed is left undissolved. On the other hand, the transparent photosensitive resin layer 30 in other regions is almost dissolved and removed, but a thin film for the transparent protective layer 15 is left (see FIG. 7 (D)). Thereafter, an oriented layer 17 is formed and predetermined curing treatment is performed to obtain a color filter substrate 2 ′′′ for an IPS color liquid crystal display.
- a negative type transparent photosensitive resin composition is used
- a well-known positive type transparent photosensitive resin composition may be used like in the example shown in FIG. 6 to form the color filter substrate 2 ′′′.
- the black matrix 12 , the colored layer 13 and the dummy colored layer 13 R′ are formed and thereafter a positive type transparent photosensitive resin layer is formed so as to cover these layers.
- the positive type transparent photosensitive resin layer is subjected to photosensitivity-reduction treatment so that the transparent photosensitive resin in the exposed region (regions other than the positions where the shielding member 14 and the columnar convex portion 18 are to be formed) is left in a desired thickness enough to form the transparent protective layer 15 .
- This treatment may be carried out by, for example, heating the transparent photosensitive resin layer at a temperature higher than the prebaking temperature used in usual photolithography. Then the positive type transparent photosensitive resin layer is exposed via a photomask for forming the shielding member 14 and the columnar convex portion 18 and developed.
- the positive type transparent photosensitive resin layer on the portions where the shielding member 14 and the columnar convex portion 18 are to be formed is left undissolved and the transparent photosensitive resin layer in other regions are almost dissolved and removed, but a thin film for the transparent protective layer 15 is formed.
- the shielding member 14 and the columnar convex portion 18 may be formed by forming a transparent resin layer corresponding to each height required for the shielding member 14 and columnar convex portion 18 and forming a resist layer at the positions, where the shielding member 14 and the columnar convex portion 18 are formed, on the transparent resin layer, followed by etching to the extent that the transparent protective layer 15 is left.
- the shielding member, the columnar convex portion and the transparent protective layer are formed of the same materials in this manner, they can be formed at the same time by the method mentioned above. Therefore, a color filter substrate provided with the shielding member, the columnar convex portion and the transparent protective layer can be produced without carrying out a new additional step. This decreases the production cost and hence the resulting color liquid crystal display can be provided at a low price.
- the driving system of the color liquid crystal display of the present invention is not limited to this.

- Photosensitive coating materials for black matrix and photosensitive coating materials for colored layer were those produced by adding beads to a dispersion composition (a pigment, a dispersant and a solvent) having the composition shown below, dispersing the composition for 3 hours by using a dispersing machine and thereafter mixing the dispersion, from which the beads were removed, with a clear resist composition (a polymer, a monomer, additives, an initiator and a solvent).
